Mechanical crust breaking automatic cleaning device for aluminum electrolysis cell

Abstract

The invention aims to disclose a mechanical crust breaking automatic cleaning device for an aluminum electrolysis cell. The device comprises a cleaning hammer and a protective plate, wherein the protective plate is arranged on one side of a crust breaking chips, and the rear end of the cleaning hammer is rotatably fixed to the protective plate; a first static pulley is arranged on an air cylindervalve head, and a second static pulley is arranged at the rear end of the protective plate; and the tail part of the crust breaking chips sequentially penetrates through the first static pulley and the second static pulley through a steel wire rope to be connected with the tail part of the cleaning hammer, and a reset spring is arranged between the front end of the cleaning hammer and the protective plate. Compared with the prior art, a crust breaking chips sticking package can be automatically processed, and an electrolyzer is prevented from knocking the crust breaking chips sticking package,so that the labor intensity of replacing the crust breaking chips by a cell maintainer is greatly reduced, the service life of the electrolytic cell crust breaking chips and the service life of the air cylinder are effectively prolonged, convenience and feasibility are achieved, time is saved, cost is reduced, and the device can also be applied to similar working conditions that surface impurities need to be removed through repeated knocking and extrusion in high-temperature and low-temperature environments in other industries besides crush breaking of the electrolysis cell.

Description

technical field [0001] The invention relates to an automatic shell-breaking device, in particular to a mechanical shell-breaking automatic cleaning device for an aluminum electrolytic cell. Background technique [0002] The aluminum electrolytic shelling system consists of a shelling cylinder and a shelling hammer. The shelling hammer is a cylindrical structure with a hollow upper part and a solid bottom made of Q235 cast iron. It is fixed on the bottom of the shelling cylinder by a snap ring. Push to reciprocate. [0003] Part of the liquid electrolyte will stick to the hammer head after each beating. Due to the high viscosity of the liquid electrolyte, it is very easy to solidify after cooling in the air. In normal production, each electrolytic cell has 6 sets of shelling mechanisms, and each set of shelling mechanisms shells once every 60 seconds. After several shellings, some shelling hammers will stick to the thick liquid electrolyte to form shell heads. . When the ...

Problems solved by technology

At this time, the electrolyzer needs to use a hammer (5 kg each) to slam the shell head bag to break the solid electrolyte and then drop it. On average, each electrolyzer consumes one hammer per shift (8 hours per shift), which greatly Increased labor intensity of electrolyzers

At the same time, due to knocking, the shelling hammer head is damaged and its frequent
